uid measuring epperetus of ehe kind adapted lo the vending of measuredamounts/of gasoline or other liquids.

The present improvement is designed to prevent improper or fraudulentuse of the nmcliine by rendering ie impossible to return to the meintank any portion of :i measured quantity or divert ie from thepurchaser, or to withdrew any liquid from the pnrehesers tank by suctionor to in any manner operate the machine lo deliver less than illeindicated measured einoun.

The invention is shown as applied to e machine like that of my priorPetennllo. 1,297,210, dated March 1l, 1919, and. utilizes e meesurmwtank into which the li uid is charged., preferably by suction, i. e.,annosplierio ypressure due to exhaustion of air from the measuring' tankthrough. o vertically adjustable feed and return pipe lieving means forpositively locating il at any predetermined 'measuring level, thesurplus returning 'therelhrouggl'i7 leaving the ineesnred amount levelwilli its top, einer which the full. contents are Withdrawn onddelirered to the purchaser, upon equalization ol atmospheric pressure.

The objects of the inveinbion are secured by Ineens of e locking' floatand leo-operaiing rotatable ebuinenl; pls-tes attached to the upperportion 0I" lie feed. and returnpipe sind. o fixed guide for the Hoetwhereby to control iis vertical movement in :i constent controlling lineolli" irevel.
